B. Strong nuclear force

C. Electromagnetic force

D. Gravity

Answer

Correct Answer is C (Electromagnetic force)

Explanation:

weak nuclear force

The weak nuclear force acts inside individual nucleons. Weak nuclear force are short ranged forces. Weak nuclear force allows protons to turn into neutrons and vice versa through beta decay.

Strong nuclear force

Strong force is responsible for binding together the particles which built up a proton or neutron. It is responsible for holding the nuclei of atoms together,

Electromagnetic forces

Electromagnetic force is the force which act between charged particles. It is the unification of two forces (electric and magnetic force.

Gravity

Gravity is a force which acts between all bodies which have mass. It always attracts objects together, and although it is the weakest fundamental force. The force of gravity pulls objects towards Earth, causing things to fall.
